Podistera nevadensis

Higher Taxonomy
Family: Apiaceae (Umbelliferae)View DescriptionDichotomous Key
Habit: Annual to perennial herb [shrub, tree], generally from taproot. Stem: generally +- scapose, generally ribbed, hollow. Leaf: basal and generally cauline, generally alternate; stipules generally 0; petiole base generally sheathing stem; blade generally much dissected, occasionally compound. Inflorescence: umbel or head, simple or compound, generally peduncled; bracts present in involucres or 0; bractlets generally present in "involucels". Flower: many, small, generally bisexual (or some staminate), generally radial (or outer bilateral); calyx 0 or lobes 5, small; petals 5, free, generally ovate or spoon-shaped, generally incurved at tips, generally +- ephemeral; stamens 5; pistil 1, ovary inferior, 2-chambered, generally with a +- conic, persistent projection or platform at tip subtending 2 free styles. Fruit: 2 dry, 1-seeded halves (= mericarps), separating from each other but generally +- persistent to central axis; ribs on halves 5, 2 marginal, 3 to back; oil tubes 1--several per interval between ribs.
Genera In Family: 300 genera, 3000 species: +- worldwide, especially temperate; many cultivated for food or spice (e.g., Carum, caraway; Daucus; Petroselinum); Bupleurum lancifolium Hornem. is historical garden weed; some toxic (e.g., Conium). Note: Mature fruit generally critical in identification, shape given in outline. Hydrocotyle moved to Araliaceae, Orogenia moved to Lomatium, Sphenosciadium moved to Angelica. Petroselinum crispum (Mill.) A.W. Hill is a waif.

Genus: PodisteraView Description 

Habit: Perennial herb, taprooted, low, fibrous at base, +- puberulent. Stem: 0. Leaf: basal; blades oblong to widely ovate, 1--2-pinnate, leaflets linear to round. Inflorescence: umbels compound, dense, head-like; bracts 0 or linear; involucel 1-sided; bractlets several, narrow or wide, generally partly fused; rays few, cylindric to flattened or winged; pedicels like rays. Flower: calyx lobes conspicuous; petals wide, yellow, +- purple, or white, tips narrowed. Fruit: oblong-ovate to ovate, +- compressed side-to-side, glabrous; ribs +- equal, thread-like to prominently corky, obtuse; oil tubes 2--several per rib-interval; fruit axis not obvious. Seed: compressed front-to-back; face flat to +- concave.
Etymology: (Greek: solid foot, from compact habit)

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
